outwardly'extending step 5i, 'fand a shoulder the last. mentioned.tongues beingshown as of 6 with a lower cylindrical portion which isgreater kwidth or angular extent than the parts 13, These tongues cooserate with a base member :tor the cap to term seats tor the endportions et the wires constituting the 4double resilient thread referredto hereinbe- 5 fore. These wires are shown in Figs. l and 6 and eachcomprises an end portion 15 which is adapted to be received outside ot alip or tongue 18, an inclined portion 15a entend ing upwardly (or towardthe cover ot l the cap) from such seat, the inclined por tion 15constituting; an operating resilient thread in eachV of said wires, theinclined or thread portion terminatingin aconcavo seat l termed bybending' each wire downwardly or toward the flan ge 12 ot'the cap or clos-ure.

From the seat 15b, each wire is bent upwardly or toward the cover of thecap,thence downwardly or toward the llanoje 12, forming a loop 15,thence behind 'i tongue 1&1, whence it is extended along;` the `erooveformed by and within the flange 12, and the extreme end is bent upwardlytoward the cover in an in clined direction, as indicated at 15d. Theinclined end 15d of each et the wires is so bent upwardly or toward thecover on the opposite side from a tongue 18 from which the inclinedportion 15CL et the complementary wire extends. The portion 15a ot onewire and the portion 15d of t-he other wire form there between aninclined channel which assists in the removal of the cap, as will bepointed out hereinafter.

lilith the wires positioned within the 'flange 12 and within the body 10and engaging` the projections or tongues 13 and 14 as described, the endportions will be preferably locked in place against such proiections bymeans of an annular base, indicated ,generally at 1G, the said basebeing ot approximately U-shape in 40 section and having; its upper oruter tlana'e 16"4 engaging the corresponding); outwardly projectingportion ot the flange 12, while its inner or bottom tlanffe 16hv thetongues 13 and 111 and extends ,radially1 inwardly beyond the same. rihelockingl basel may be secured in place by spinningl the metal thereoiCabout the flange 1Q, about the portions of the wires 15 within suchflange, and about the tongues 13 and 14. 5o This construction anchorsthe end portions of the wires securely in place and provides auornamental iinish 'for the cap. In linel with the tono/'ues 13, thetiaupge 1G" notched` as indicated at 1T, for the reception of the pinsor studs 9. Tlf-ith the parts cr'mstructed and arranged as describedythe cap will be applied' to the radiator neck by aligning the notches1i' with the ystuds or pins 9 and by pressing downwardly upon the'capand then rotating it from left to right in the direction et the ordinaryscrewtbread. This will cause the pins 9 to follow in the channelsprovided between the parts 15a and 15d and to engage above the inclinedparts 15a. These parts, t'ornriing,r the double resilient thread.

neeefiv'v "ill, by the time the lower or inner portions ot' the parts l5shall have reached the studs 9, have drawn the cap tirmly to itsseaawieh the casket 11 engaging.)T the outer end ot the part and theflange 1b*J engaging the part" 5 and 8, at"$.vhich time the studs orpins will snap into the seats 15b and further movement in a locking'direction will be resisted by the parts 15. 1When it is desired toremove the cap, it is only necessary to turn it .firmly in the oppositedirection. This will result in disengaging the pins or studs trom theseats 15'. As the cap is rotated to the lett, the portions ot the wires15d `will lass above the' studs or pins 9 and, in cooperation with thenotches, willifacilitate the unseating of the cap.

is the cap heroin shown and described is intended for use with aradiator, it is desirable that it be not heated to a temperaturel whichwill prevent it tre-in being operated by hand. To prevent it frombecoming so overhcated, it is provided with openings l()b formed in theskirt or cylindrical portion 10, said openings permitting` circulationoi? air through the cap. rllhis circulation oi air will largely preventthe overheating ot the. cap referred to and enable it to be handled bythe operator. n.

9While the parts 9 have been referred to as pins or studs, it will beevident that any projections suitable to engage the resilient threads15@ will secure the saine result as such pins or studs. Hence, bytheuseof theeX- pression pins or studs I do not propose to'be limited toany particular style oit. project-ions, provided that they are capableet cooperating; with the said threads to draw the cap to itsY seat.Furthermore, while l have. shown and described wires as employed for theresil-` ient locking members, I do not propose thereby to limit myselfto the use et any particular cross-section in the material employed torsuch threads. Y t

For the. purpose ot securing a cheap and eiiicient n'iountinp; et thepins or studs on the filling' neck, each pin or stud is constructed inthe manner shown more particularly in Fig; 9, As will be seen from thisview, each pin or stud comprises head EfL adapted to enthe inner surfaceof the neck, a boe y poi ion 9b adapted to lit within the opening' prvided therefor in such neck, and a reduced threadengaging portion 9"'.rl'he body portion 9b is oi slight-ly gre-atei' length tl an thethickness of the stock of the neck, thereby enabling` the annularportion 9d to be peened outwardly into engagement with the outer face ofthe neck. This provides a cheap and etlicient manner of mounting,` thepins or studs on such neck.
